A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER ! You will find that password in ‘/root/.mysql_secret‘.

You must change that password on your first connect, no other statement but ‘SET PASSWORD‘ will be accepted. See the manual for the semantics of the ‘password expired‘ flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test database. This is strongly recommended for production servers.

See the manual for more instructions.

Please report any problems at http://bugs.mysql.com/

New default config file was created as /usr/my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings

安装成功后,默认端口号时3306.

3、相关命令
     /usr/bin(mysqladmin   mysqldump等命令)
 
     4、启动脚本
     /etc/rc.d/init.d/(启动脚本文件mysql的目录)

    如:/etc/rc.d/init.d/mysql   start/restart/stop/status

由于MySQL数据库目录占用磁盘比较大,所以我在/根目录下建了个个目录data,命令如下:

[root@Linux bin]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1             50786236   2478688  45686144   6% /
/dev/sda3            306748620   5803348 285112012   2% /usr
tmpfs                  1763232         0   1763232   0% /dev/shm
[root@Linux bin]# cd /usr
[root@Linux usr]# ls
bin  games    java      lib    libexec  lost+found  sbin   src  workfiles
etc  include  kerberos  lib64  local    my.cnf      share  tmp  X11R6
[root@Linux usr]# mkdir data

)把数据库移动到data目录中去。输入以下命令:

# mv  /var/lib/mysql  /usr/data

最后,进入data目录就会看到有一个mysql文件夹。

[root@Linux mysql]# cd /etc/rc.d/init.d

[root@Linux init.d]# vi mysql

basedir=
datadir=/usr/data/mysql   保存即可。

 [root@Linux usr]# mysql -u root -p -S /usr/data/mysql/mysql.sock
Enter password:
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/usr/data/mysql/mysql.sock‘ (111)
[root@Linux usr]# ps -A |grep mysql
22677 pts/4    00:00:00 mysqld_safe
22780 pts/4    00:00:00 mysqld
[root@Linux usr]# kill -9 22677
[root@Linux usr]# kill -9 22780
[root@Linux usr]# service mysql start
Starting MySQL                                             [  OK  ]
[root@Linux usr]# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)

ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: NO)

于是重改密码!

# /etc/init.d/mysql stop

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

# mysql -u root mysql

mysql> UPDATE user SET Password=PASSWORD(‘newpassword‘) where USER=‘root‘;

mysql> FLUSH PRIVILEGES;

mysql> quit

# /etc/init.d/mysqld restart

# mysql -u root -p

Enter password:

mysql> 

 

卸载Mysql

1、查找以前是否装有mysql

命令:rpm -qa|grep -i mysql

可以看到mysql的两个包:

mysql-4.1.12-3.RHEL4.1

mysqlclient10-3.23.58-4.RHEL4.1

2、删除mysql

删除命令:rpm -e --nodeps 包名

( rpm -ev mysql-4.1.12-3.RHEL4.1 )

3、删除老版本mysql的开发头文件和库

命令:rm -fr /usr/lib/mysql

rm -fr /usr/include/mysql

注意:卸载后/var/lib/mysql中的数据及/etc/my.cnf不会删除,如果确定没用后就手工删除

rm -f /etc/my.cnf

  rm -fr /var/lib/mysql
